Airtac SE125 Standard Cylinder SE125X1100S
The AirTAC Airtac SE125 Standard Cylinder SE125X1100S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 1100mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X1100S
The AirTAC SE125X1100S is a double-acting single-rod profile cylinder built to ISO 15552 dimensional standards, delivering a substantial 6136 N push force at 0.5 MPa. Its clean extruded aluminum barrel omits external tie rods entirely, yielding a compact body that mounts flush against machine frames while resisting corrosion. The integrated -S magnet enables direct position tracking using AirTAC CMSE reed or DMSE electronic sensors housed neatly in the body's three sensor grooves.
Because the 1100 mm stroke exceeds the catalog maximum of 1500 mm for this bore, this specific configuration is handled as a non-standard made-to-order build. The 32 mm piston rod and M27x2 rod-end thread provide a robust interface for heavy loads, while the field-adjustable air cushioning at both ends allows technicians to dial in the exact deceleration needed to soften hard end stops at speed.

Where the Airtac SE125 Standard Cylinder SE125X1100S Is Used
Automotive Body Panel Press
Provides the 8590 N push force at 0.7 MPa required to form and stamp heavy-gauge automotive body panels over the extended 1100 mm travel distance.
Heavy Lumber Sorting Gate
Actuates large diverter gates in sawmills, utilizing the 125 mm bore's 5734 N pull force to reliably shift heavy timber loads along the processing line.
Palletizer Layer Forming
Lowers heavy layer-forming heads in end-of-line palletizing cells, relying on the built-in magnet and DMSE sensors to confirm positioning across the long stroke.
Is the Airtac SE125 Standard Cylinder SE125X1100S the Right Cylinder?
Selecting this 125 mm bore cylinder makes sense when your application requires the maximum standard pneumatic thrust available in the SE range, generating 6136 N of push at 0.5 MPa. If your load requirements are lighter, stepping down to the 100 mm bore reduces the footprint and yields 3927 N of push at 0.5 MPa; as the largest standard SE bore, there is no larger neighbor to step up to within this series. At 1100 mm of travel, the unsupported mass of the 32 mm rod introduces significant rod-bearing bending risks under side load, so an external guide mechanism is mandatory to prevent premature seal failure.
This unit is dimensionally interchangeable with other ISO 15552 cylinders, meaning you can drop it directly into existing footprints and reuse standardized mounting accessories like TC centre trunnions or CA clevises. Remember that the adjustable air cushion only decelerates the piston near the stroke ends—it does not function as a locking device. If the machine loses air pressure or the valve is centered, the load will drift, requiring a BSE rod lock or external pilot-operated check valve for secure holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X1100S FAQ
This 125 mm bore cylinder features a PT1/2 port and generates 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, and it reaches a maximum push of 1252 kgf at 1.0 MPa. The operating speed range is 30-500 mm/s.
Yes, the SE125X1100S is dimensionally interchangeable per ISO 15552 standards. You can drop it directly into existing footprints and reuse standardized mounting hardware, though you should confirm the non-standard 1100 mm stroke fits your existing envelope.
